CVE-2024-34344 in Nuxt
Summary
by MITRE • 08/06/2024
Nuxt is a free and open-source framework to create full-stack web applications and websites with Vue.js. Due to the insufficient validation of the `path` parameter in the NuxtTestComponentWrapper, an attacker can execute arbitrary JavaScript on the server side, which allows them to execute arbitrary commands. Users who open a malicious web page in the browser while running the test locally are affected by this vulnerability, which results in the remote code execution from the malicious web page. Since web pages can send requests to arbitrary addresses, a malicious web page can repeatedly try to exploit this vulnerability, which then triggers the exploit when the test server starts.

Analysis
by VulDB Data Team • 03/16/2025
This vulnerability exists within the Nuxt framework's test component wrapper functionality where inadequate input validation permits path parameter manipulation leading to server-side code execution. The flaw specifically resides in how the NuxtTestComponentWrapper processes the path parameter without sufficient sanitization or validation checks, creating an attack vector that allows remote code execution through malicious web pages. The vulnerability is particularly dangerous because it enables arbitrary JavaScript execution on the server when users open compromised web pages while running local test environments, making it a critical security concern for developers working with Nuxt applications.
The technical implementation of this vulnerability stems from improper parameter handling within the test component wrapper mechanism. When the path parameter is processed without adequate validation, attackers can inject malicious JavaScript code that gets executed server-side during test operations. This represents a classic server-side code injection vulnerability that aligns with CWE-94, which describes the execution of arbitrary code or commands. The attack surface is expanded by the fact that web pages can make requests to arbitrary addresses, allowing malicious actors to repeatedly probe for the vulnerability until they successfully trigger the exploit when the test server is active.
The operational impact of this vulnerability is severe as it enables remote code execution from malicious web pages, potentially allowing attackers to compromise entire development environments. When developers run local test servers and open malicious web pages, the vulnerability can be exploited to execute arbitrary commands on the server, leading to potential data breaches, system compromise, and unauthorized access to development resources. This threat model aligns with ATT&CK technique T1190, which covers exploiting vulnerabilities in web applications, and T1059, which involves executing commands through various interfaces including web-based attack vectors. The vulnerability affects not just production environments but also local development setups, making it particularly concerning for security-conscious development teams.
Organizations and developers should immediately implement mitigations including updating to patched versions of Nuxt framework components, implementing strict input validation for all path parameters in test environments, and restricting access to local test servers from untrusted networks. Additional protective measures include disabling test components in production environments, implementing network segmentation for development servers, and conducting regular security assessments of development environments. The vulnerability highlights the importance of secure coding practices and proper input validation, particularly in testing frameworks where developers may not expect security considerations to apply. Security teams should also monitor for exploitation attempts and ensure that local development environments are properly secured to prevent unauthorized access to sensitive test configurations and data.
